Every movie about a strike needs a heroine, someone brash enough to stand on top of a table with a megaphone and demand justice.

But some credit for the possible ending of the three-month-old strike by the Writers Guild of America may be going to a different sort of heroine.

New York Times reporter Michael Cieply writes today that Laeta Kalogridis, most recently the executive producer of Bionic Woman, helped bring the warring parties together not with a megaphone but with a phone and with e-mail.

Celebrity support, always important in national campaigns, is likely to play an increasing role in the high-cost, heated presidential campaign of 2008.

When it comes to good-looking supporters, Barack Obama leads the pack, with Scarlett Johansson, Jennifer Aniston, Halle Berry, Jamie Foxx, and George Clooney. And of course, there’s his powerhouse stumper, Oprah Winfrey.

Hillary Clinton is backed by a slightly older, more established, show business crowd which includes Chevy Chase, Danny DeVito, Rob Reiner and Steven Spielberg.
